--------------------------------
Summary: Ensure sub-application user is extracted & sent to
timeline service
Key: YARN-6734
URL: https://issues.apache.org/jira/browse/YARN-6734
Project: Hadoop YARN
Issue Type: Sub-task
Reporter: Vrushali C
After a discussion with Tez folks, we have been thinking over introducing a
table to store sub-application information. YARN-6733
For example, if a Tez session runs for a certain period as User X and runs a
few AMs. These AMs accept DAGs from other users. Tez will execute these dags
with a doAs user. ATSv2 should store this information in a new table perhaps
called as "sub_application" table.
YARN-6733 tracks the code changes needed for table schema creation.
This jira tracks writing to that table, updating the user name fields to
include sub-application user etc. This would mean adding a field to Flow
Context which can store an additional user
